Aquaculture-driven evolution: distribution of pyrethroid resistance in the salmon louse throughout the North Atlantic in the years 2000–2017
(Journal article; Peer reviewed, 2020)The parasitic salmon louse, and its documented resistance to chemotherapeutants, represents the most persistent environmental challenge to global salmonid aquaculture. We used a genetic marker associated with pyrethroid ... -
A combination of genetic and phenotypic characterization of spring- and autumn-spawning herring suggests gene flow between populations
(Journal article; Peer reviewed, 2020)Atlantic herring (Clupea harengus) has complex population structure and dynamics including diverse life histories and spawning times with spring and autumn spawning as the most common modes. Originally, spawning herring ... -
Density-independent mortality at early life stages increases the probability of overlooking an underlying stock-recruitment relationship
(Journal article; Peer reviewed, 2021)Abstract Beverton and Holt’s (1957) monograph contributed a widely used stock–recruitment relationship (BH-SRR) to fisheries science. However, because of variation around a presumed relationship between spawning biomass ... -
Eight decades of adaptive changes in herring reproductive investment: the joint effect of environment and exploitation
(Journal article; Peer reviewed, 2021)Reproductive investment is a central trait for population dynamics and productivity. Fishing and environmental variations are major drivers affecting population structure, dynamics, and adaptation of life-history and ... -
Flexible behaviour in a mesopelagic fish (Maurolicus muelleri)
(Journal article; Peer reviewed, 2021)Variability of mesopelagic scattering layers is often attributed to environmental conditions or multi-species layer composition. Yet, little is known about variation in behaviour among the individuals forming scattering ... -
How trophic cascades and photic zone nutrient content interact to generate basin-scale differences in the microbial food web
(Journal article; Peer reviewed, 2020)In linear food chains, resource and predator control produce positive and negative correlations, respectively, between biomass at adjacent trophic levels. These simple relationships become more complex in food webs that ... -
Pre-catch and discard mortality in Northeast Atlantic herring and mackerel fisheries: consequences for stock estimates and advice
(Journal article; Peer reviewed, 2021)Unaccounted mortality caused by discarding or pre-catch losses is a major challenge for fisheries management. In pelagic fisheries, a considerable proportion of catches may be lost due to intentional release of unwanted ... -
Stable oxygen isotope reconstruction of temperature exposure of the Icelandic cod (Gadus morhua) stock over the last 100 years
(Journal article; Peer reviewed, 2020)Increasing water temperatures are predicted around the globe, with high amplitudes of warming in Subarctic and Arctic regions where Atlantic cod (Gadus morhua) populations currently flourish. We reconstructed oxygen isotope ...
